Definition: In this task, you are given inputs i,j, and A, where i and j are integers and A is a list. You need to return the sum of all the numerical elements in the list A between the positions i and j (including positions i and j). Return 0 if no numerical element is present in the list between the given ranges. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j.
Input: 14, 18, ['u', '649', 'A', '3683', '5549', 'd', 'S', 'O', '1589', '163', '7773', 'a', 'J', 'z', '9529', 's', '3821', '7851', '1375']
